  2. aComprehensive lists of transcription factors that interact with p300/CBP (Kasper et al., 2006) and Brg1 (Trotter and Archer, 2008) are shown elsewhere.
  3. bAlthough the canonical mechanism of DNA binding is through E2Fs, at least three subdomains of pRb can directly bind DNA (Wang et al., 1990).
